a housing surrounding the .container from which liquid is to be dispensed. This housing makes the dispenser relatively bulky and expensive and has the further disadvantage thatthe dispenser can be attached only to a container of a definite diameter. Objects of my invention are'to do Without'such housing, thereby to reduce the 'measures, the cost and the weight of the dispenser,-and'to provide a dispenser that can be .flrmly'attached to containers of different diameters." r

" Other objects are to provide the dispenser with a cutter that opens the container while the'dispenser is" being attachedto'the same, to utilize the-cutter forthisattachment, to secure a lateral wall of the container between gripping surfaces of the cutter and of a plate-shaped part of the dispenser, to arrange the gripping parts in such a manner that they contact the container wall along spaced lines whereby the gripped part of this wall can bend resiliently, thereby to facilitate a reliable attachment of the dispenser to walls of different thickness or of difi'erent curvature.

Further objects are to provide the dispenser with-a drip chamber receiving liquid flowing back from the outlet funnel of the dispenser when the same is placed down in upright position and releasing this liquid into the funnel when the dispenser is tilted'again for use, to combine'the drip chamberwith the gripping plate, to secure a ready and smooth outflow from the dispenser,

and to provide the dispenser with an inlet for air replacing the dispensed liquid.

Still other objects are to provide the dispenser with a cutter that cuts out a broad strip from the wall of the container and bends this strip in a manner forming a wide opening, to use the cutter as a channel guiding the liquid through this opening into the funnel, and to afiix the cutter to the funnel detachab ly whereby the cutter can be easily adjusted and can be replaced when its cutting edge has become blunt.

Still other objects and advantages will appear from the following description of an exemplifying embodiment of my invention, from the appended claims and from the accompanying drawing in which:

Fig. 3 shows'a cross-section takenalongthe line 3-3 inFig.1;v 1

Fig. 4 showsfa cross-section taken .along "the line4--4inFig-.1.

Referring to the drawing, numeral'jz indicates a funnel comprising an elongated;suitably-directed tube extending from a funnel part :5-w hich, in attached'condition or the embodimentyabuts an end 'wallfi" of a cylindrical container 1. The abutting end'of the funnel may be-br'oadened by wing plates "or flanges 8. An end portioniof the wall'9 of the funnel'part" 5 is'cutout whereby this part is providedwith a broad lateralo'penllng I I. The walls 12 of the funnel'part-i-have projections l3 extending at "opposite'sides of :the

opening ll'beyond thewallil;

A plate 1.4 is affixed to the lower 'side'of the funnel part 5 or'of its Wings 8 and extends therefrom vertically down. In attached condition of the dispenser, this plate contacts the outside of the containers lateral wall 15'. The'plat'e "M is preferably slightly curved in a manner correspending to the'curvature of the wall l5fmay' be somewhat broader than the funnel part I 5, but is considerably narrower than the circumference .of'the wall [5.The central'upper portion of'the A cutter 2| has an upper part 22 shaped like a vertical channel and fitting between the walls I2 of the funnel part 5. The channel 22 preferably projects beyond the funnel wall 9, for example, as far as the extensions l3 of the walls I2. Thereby, the upper opening of the channel 22 is not completely covered by the funnel, and a slot is left open at 23 which slot acts as an inlet for air replacing the liquid dispensed from the container. This replacement maintains normal air pressure in the container and, hence, facili tates a smooth and uniform outflow of liquid.

That side 24 of the channel 22 which is opposite to the side which is flush with the extensions [3 may be round and has a downwardly extending continuation 25 shaped like a pointed shovel and provided with sharp cutting edges. The cutting shovel 25 has a vertical back line which, in attached condition, contacts the inside of the container wall 15 along a line juxtaposed to the channel [7.

Preferably, the cutter 2| has a rib 26 forming an inner projection of the channel 22 and extending down beyond this channel spaced from and along the concave side of the shovel 25. The downward extending part of the rib 26 tapers and has an oblique edge pointing toward the end portion of the shovel 25. This rib contributes to the cutting and opening action of the cutter.

The cutter 2| is preferably removable and, hence, replaceably aifixed to the other :parts of the dispenser, for example, by screws 27 which pass through the walls I2 and through the adjacent walls of the cutter channel 22 and which are secured by nuts 28.

The originally sealed container '1 is opened by piercing through the end wall 6 with the pointed end of the cutting shovel 25 at a point close to the edge of this wall and by forcing the dispenser down until the wings '8 contact the wall 6 whereupon the device is in the position shown in Figs. 1, 3 and 4. Thereby a strip or flap 29 is cut out of the wall 6, except that this flap remains connected to the remaining wall along a line 3 I. At the same time, the flap is bent inwardly about the line 3|.

During this downward movement, the device is guided along the lateral wall I5 of the container by the plate I4 sliding along the outside and. by the shovel 25 sliding along the inside of this wall. After the device has reached the shown position, it .is firmly attached to the container, the wall [5 of which is resiliently compressed between the shovel 25 contacting this wall along a line juxtaposed to the window [6 and between the plate 14 contacting this wall along lines laterally spaced from the contact line of the shovel.

After the dispensing device has been attached in the manner described, liquid may be dispensed from the container by tilting the latter as far as necessary in order to cause liquid to flow through the channel formed by the cutter 21 into the funnel 2. r

I desire it understood that my invention is not confined to the particular embodiment shown and described, the same being merely illustrative,

and that my invention may be carried out in other ways without departing from the spirit of my invention as it is obvious that the particular embodiment shown and described is only one of the many that may be employed to attain the objects of my invention.

Having described the nature of my invention, what I claim and desire to protect by Letters Patent is:

1. A device for dispensing liquid from a container having end walls and a lateral wall, said device comprising a funnel forming a rising tube narrowing toward its upper end, a plate extending from said funnel downwardly, having a horizontal width smaller than one-half. of the circumference of said lateral con-tainer wall and contacting the outside of said lateral wall unilaterally when said device is attached to said container, a channel leading from said funnel along the outside or" said plate and having a closed bottom whereby said channel forms a drip chamber, and a cutter afiixed to said funnel in a fixed position, extending along said plate less far than said channel and contacting the inside of said lateral wall in said attached condition whereby said lateral wall is firmly gripped by said plate and said cutter, said plate comprising the inner wall of said drip chamber and having an inter.- rupvlon extending along that part of said channel which extends along said cutter.

2. A device for dispensing liquid from a con tainer having end wall and a lateral wall, said device comprising a funnel forming a rising tube narrowing'toward its upper end, a plate extending from said funnel downwardly, having a horizontal width smaller than one-half of the circumference of said lateral container wall and contacting the outside of said lateral wall unilaterally when said device :is attached to said container, a central upper portion of said plate being cut out, and a cutter aflixed to said tunnel in a fixed position, shaped like a pointed shovel, having a rib pointing toward the end of said :shovel and having a back extending along said out out portion of said plate and, contacting the inside of said lateral wall in said attached condition whereby said lateral wall is firmly gripped by said plate and said cutter.
